Universal 11x22mm Stem Fit

This five-pack of replacement caster wheels uses a 7/16" x 7/8" stem size that matches roughly 98% of standard office chairs, excluding IKEA models. Installation requires no tools; the old casters pull out and the new ones push in by hand. The set restores mobility to desk and gaming chairs in under a minute.

1000 lbs Capacity with Dust Cover

Each wheel supports up to 1000 lbs, providing ample headroom for heavy users and loaded seating. The integrated dust cover blocks pet hair and carpet fibres from wrapping the axle, eliminating the need to flip the chair for cleaning and extending the service life of the casters.

360° Swivel on All Floor Types

High-carbon steel bearings enable full 360° rotation, allowing responsive directional changes and sideways movement with minimal effort. The soft polyurethane tread runs quietly on wood, hardwood, laminate, tile and carpet, preventing disruptive squeaks in shared workspaces.

Questions about this item

Will the 11x22mm stem on these Metra BanGongLun-05 casters fit the chair base I already have?

The stem measures 11 x 22 mm (7/16" x 7/8") and matches roughly 98% of office chairs on the market, though it is not compatible with IKEA models.

How can I confirm the 360° swivel and quiet roll are working once installed?

Push the chair in several directions; the high-carbon steel bearings should rotate a full 360° with minimal effort and the soft polyurethane tread should produce very little noise on hard floors or carpets.

Does the 5-pack include everything needed for installation, or are extra parts required?

The set contains five complete caster wheels with integrated dust covers; no tools or additional hardware are required — simply pull out the old casters and press the new stems in by hand.
